# Showcase

The full XWUIBarcodeEAN5 range on one screen: the strict five-digit payload, the book trade price convention it usually carries, bar geometry (module width, height, quiet zone), and every knob on the human-readable digit line.

It closes with a back cover block and a live re-encode driven by `setData()`. The parity pattern is derived from the weighted checksum of the five digits, so nothing extra has to be supplied. Bars stay black on white because scanner contrast is a hard requirement, so the canvas ink is deliberately not themed.
